Cisco CCNA Certification: Should You Take The One

Cisco CCNA Certification: Should You Take The OneExam or TwoExam Approach?

by: Chris Bryant, CCIE #12933

One question I’m often asked by CCNA candidates is whether to take the ขone big examข, or take the two separate exams required by Cisco to achieve the Cisco Certified Network Associate (CCNA) exam.

The question comes up because there are now two separate paths to the CCNA certification. Candidates may take a single exam, 640811, or two exams, 640821 and 640811.

What’s the difference? The twoexam approach involves exams with different topics and therefore different preparation techniques. 640821 is the Introduction To Cisco Networking Technologies exam. This course does introduce the candidate to Frame Relay, PPP, and other WAN technologies, but goes into little detail. Emphasis in the Intro course is placed on knowing how Ethernet behaves, how different types of cable are used for different purposes, and knowing what cable to use in a certain situation. The candidate should expect some questions involving binary math as well, but they will involve fairly simple conversions.

The 640811 exam, Interconnecting Cisco Networking Devices, goes into much more detail on WAN technologies. Routing and switching behavior are covered, and the candidate is expected to answer difficult questions involving binary math and subnetting as well. The candidate may also have to demonstrate ability to configure a router or switch via a simulator. Since the ICND exam goes into more detail, it’s generally considered the more difficult exam.

The approach I recommend to a CCNA candidate depends on their background. If the candidate is a relative newcomer to networking, or hasn’t taken a certification exam before, I recommend they take the twoexam approach. This allows the candidate to focus only on the Intro topics, and gives them a strong sense of confidence after passing the Intro exam. That confidence flows over into the ICND exam.

For those who have networking experience, and are very familiar with Ethernet behavior and cable types, I recommend the oneexam approach. This allows the candidate to focus on the more advanced topics they’ll be seeing in the single exam, while spending just a little time reviewing their Introlevel knowledge.

Regardless of the approach you choose, the path to true CCNA success remains the same. Get some real handson experience, either by renting rack time online or by putting together your own home lab. Understand what’s going on ขbeneath the commandข; don’t use router commands when you don’t understand what they’re doing. Add to that a true mastery on binary math, and you’re on your way to having the magic letters ขCCNAข behind your name!

Cisco CCNA Certification: Five Things To Do DURING

Cisco CCNA Certification: Five Things To Do DURING The Exam

by: Chris Bryant, CCIE #12933

There are plenty of articles out there about how to prepare for the CCNA exam. However, there are also things you can do to increase your chances of success on exam day during the most important part of the entire process the time that you’re actually taking the test.

Iกve taken many a certification exam over the years, and helped many others prep for theirs. Here are the five things you must do on exam day to maximize your efforts.

1. Show up on time. Yeah, I know everyone says that. The testing center wants you there 30 minutes early. So why do so many candidates show up late, or in a rush? If you have a morning exam appointment, take the traffic into account. If itกs a part of town you don’t normally drive in during rush hour, you might be surprised at how much traffic you have to go through. Plan ahead.

2. Use paper, not the pad. Some testing centers have gotten into the habit of handing exam candidates a board that allegedly wipes clean, along with a marker that may or not be finepointed. You do NOT want to be writing out charts for binary math questions, or coming up with quick network diagrams, with a dull magic marker. Itกs also my experience that these boards do not wipe clean well at all, but they smear quite badly.

Ask the testing center employee to give you paper and a pen instead. I haven’t had one refuse me yet. Remember, you’re the customer. Itกs your $100 $300, depending on the exam.

3. Use the headphones. Most candidates in the room with you understand that they should be quiet. Sadly, not all of them do. Smacking gum, mumbling to themselves (loud enough for you to hear, though), and other little noises can really get on your nerves in what is already a pressure situation. In one particular testing center I use, the door to the testing room has one setting: กSlamก.

Luckily, that center also has a headset hanging at every testing station. Call ahead to see if yours does. Some centers have them but don’t leave them at the testing stations. Wearing headphones during the exam is a great way to increase your powers of concentration. They allow you to block out all noise and annoyances, and do what you came to do pass the exam.

4. Prepare for the กWHAT??ก question. No matter how wellprepared you are, thereกs going to be one question on any Cisco exam that just stuns you. It might be offtopic, in your opinion; it may be a question that would take 20 of your remaining 25 questions to answer; it might be a question that you don’t even know how to begin answering. I have talked with CCNA candidates who got to such a question and were obviously so thrown off that they didn’t do well on any of the remaining questions, either.

There is only one thing to do in this situation: shrug it off. Compare yourself to a majorleague pitcher. If he gives up a home run, he can’t dwell on it; heกs got to face another batter. Cornerbacks in football face the same problem; if they give up a long TD pass, they can’t spend the next 20 minutes thinking about it. They have to shrug it off and be ready for the next play.

Don’t worry about getting a perfect score on the exam. Your concern is passing. If you get a question that seems ridiculous, unsolvable, or out of place, forget about it. Itกs done. Move on to the next question and nail it.

5. Finish with a flourish. Ten questions from the end of your exam, take a 15to30 second break. You can’t walk around the testing room, but you can stand and stretch. By this point in the exam, candidates tend to be a little mentally tired. Maybe you’re still thinking about the กWHAT??ก question. Don’t worry about the questions youกve already answered they’re done. Take a deep breath, remember why you’re there to pass this exam and sit back down and nail the last ten questions to the wall.

Before you know it, your passing score appears on the screen!

Now on to the CCNP ! Keep studying !

Cisco CCNA Certification: The Joy Of Hex

Cisco CCNA Certification: The Joy Of Hex

by: Chris Bryant, CCIE #12933

Cisco certification candidates, particularly CCNA candidates, must master binary math. This includes basic conversions, such as binarytodecimal and decimaltobinary, as well as more advanced scenarios involving subnetting and VLSM.

There’s another conversion that might rear its ugly head on your Cisco exam, though, and that involves hexadecimal numbering.

Newcomers to hexadecimal numbering are often confused as to how a letter of the alphabet can possibly represent a number. Worse, they may be intimidated – after all, there must be some incredibly complicated formula involved with representing the decimal 11 with the letter ขbข, right?

Wrong.

The numbering system we use every day, decimal, concerns itself with units of ten. Although we rarely stop to think of it this way, if you read a decimal number from right to left, the number indicates how many units of one, ten, and one hundred we have. That is, the number ข15ข is five units of one and one unit of ten. The number ข289ข is nine units of one, eight units of ten, and two units of one hundred. Simple enough!

Hex numbers are read much the same way, except the units here are units of 16. The number ข15ข in hex is read as having five units of one and one unit of sixteen. The number ข289ข in hex is nine units of one, eight units of sixteen, and two units of 256 (16 x 16).

Since hex uses units of sixteen, how can we possibly represent a value of 10, 11, 12, 13, 14, or 15? We do so with letters. The decimal ข10ข is represented in hex with the letter ขaข; the decimal 11 with ขbข; the decimal ข12ข with ขcข, ข13ข with ขdข, ข14ข with ขeข, and finally, ข15ข with ขfข. (CCNA candidates will remember that a MAC address of ขffff.ffff.ffffข is a Layer 2 broadcast.)

Practice Your Conversions For Exam Success

Now that you know where the letters fall into place in the hexadecimal numbering world, you’ll have little trouble converting hex to decimal and decimal to hex – if you practice.

How would you convert the decimal 27 to hex? You can see that there is one unit of 16 in this decimal; that leaves 11 units of one. This is represented in hex with ข1bข – one unit of sixteen, 11 units of one.

Converting the decimal 322 to hex is no problem. There is one unit of 256; that leaves 66. There are four units of 16 in 66; that leaves 2, or two units of one. The hex equivalent of the decimal 322 is the hex figure 142 – one unit of 256, four units of 32, and 2 units of 2.

Hextodecimal conversions are even simpler. Given the hex number 144, what is the decimal equivalent? We have one unit of 256, four units of 16, and four units of 4. This gives us the decimal figure 324.

What about the hex figure c2? We now know that the letter ขcข represents the decimal number ข12ข. This means we have 12 units of 16, and two units of 2. This gives us the decimal figure 194.

Tips For Exam Day

Practice your binary and hexadecimal conversions over and over again before you take your CCNA exams. Binary math questions come in many different forms; make sure you have practiced all of them before exam day. The number one reason CCNA candidates fail their exam is that they’re not prepared for the different types of binary math questions they’re going to be asked, and that they aren’t ready for hexadecimal questions at all.

You don’t have time to learn how to do in on exam day. You’ve got to be ready before you go into the exam room, and the only way to be ready is a lot of practice.

Finally, make sure you read the question carefully. You’ve got hex, decimal, and binary numbers to concern yourself with on your CCNA exams. Make sure you give Cisco the answer in the format they’re looking for.

Cisco CCNA / CCNP Certification: Learning To Navig

Cisco CCNA / CCNP Certification: Learning To Navigate Ciscoกs Online Documentation

by: Chris Bryant, CCIE #12933

When studying for your Cisco CCNA, CCNP, or CCIE exam, you’ve got a powerful online weapon at your disposal. It’s Cisco Connection Documentation, found at www.cisco.com/univercd. This site contains product, code, and protocol documentation for all Cisco products.

Many exam candidates really don’t start using this powerful tool until they’re studying for their more advanced exams. However, it’s important for CCNAs, CCNPs, and candidates for these certifications to learn their way around this site. It comes in handy for finding default values that Cisco really enjoys asking about on exams, and the protocol documentation found there can help you study as well.

The site can be a little overwhelming for newcomers, but it’s actually easy to navigate. On the site’s homepage, you’re presented with a list of products and several dropdown menus. To get started, I suggest you choose ขCisco IOS Softwareข in the topright dropdown menu, and select a code version. 12.2 is a good one to start with. From there, select the IOS Release 12.2 Configuration Guide and Command References.

You’re then presented with a list of technologies, and each has a Configuration Guide and a Command Reference. If you’re studying Interior Gateway Protocols at this point (such as OSPF, RIP, and EIGRP), select ขIP Configuration Guideข and then ขIP Routing Protocolsข.

You then have the official Cisco documentation on how to configure RIP, IGRP, OSPF, EIGRP, ISIS, and BGP. Reading this documentation is invaluable. Many study guides skip the details to give you an overview of the protocol. This documentation doesn’t skip anything. The documentation shows how and when to use any command for that protocol. There are also realworld examples and notes on when to use each command. I’ve always learned something new when reading the online Cisco documentation.

You can then back out and go through the same steps for the Command Reference. For those studying for Cisco exams, this section will quickly answer any question you have about a command’s syntax or default values. Instead of trying to remember which book you saw a value in, just zoom out to this site and you’ll have your answer in seconds. Realworld examples of command usage are prevalent as well.

As with anything, the more you use the online Cisco documentation, the better you get at it. The Configuration Guide for the various Cisco switches give you a great picture of how switches work. I highly recommend reading at least one of their switches’ config guides.

Beyond any exam value the online Cisco documentation gives you, it serves another valuable purpose. The more you use it now, and the more comfortable you get with it, the better you’ll be with it when the day comes that you need it on the job. And trust me – that day will come!
